MATLAB: 3d plotting help

3dhomeworkmeshmeshgridplotsurf

I am trying to plot this figure, an airplane wing but I can't seem to get it oriented right. This is the only way I could get it to plot but I want it facing me, not downward as it is now. So x is the x-axis, y is the z-axis, and z is the y-axis. Every time I change something I get an error. Please help. Thank you.

c=1;
t=0.2;
x=linspace(0,c,100);
l=linspace(0,4,100);
y=t*c/0.2*(0.2969*sqrt(x/c)-0.1260*(x/c)-0.3516*(x/c).^2+0.2843*(x/c).^3-0.1015*(x/c).^4);
[X,Z]=meshgrid(x,l);
surf(X,y,Z);
hold on;
surf(X,-y,Z);

Best Answer

You know the definition of you x, y and z axis. If you want to swap axis, why don't you change the x,y,z symbol in your equation and re-generate the plot.
Or you can use view() to set the viewpoint.
Or you can use the "Rotate 3D" button on the figure to rotate the figure to what you want, and then use the view() to get the viewpoint.
Or I modified your code.
